With Alma's help, Luke discovers his own innate ghost powers and uncovers the terrible truth of why Tabatha is kidnapping children and forcing them to shovel coal. Desperate to escape, Luke teams up with Alma, his best friend Ravi, and new girl Jess. Can Luke and his friends set themselves free before they each become victims to a cruel and sinister scheme?
